fix(styleguide): fixes #337 #338 #339; builds from LESS files

Went ahead and fixed the other two issues because they were small enough to tackle in one PR. 

I also updated the task to build from the LESS files. This introduces an error with the top nav bar, but I'll open another issue to address that.
